Comment (by olly):

 I've added a command to find the git commit corresponding to a given SVN
 revision number to https://xapian.org/bleeding :

 {{{#!sh
 git log --grep '^git-svn-id: .*@12345 ' `git branch --list -r
 'origin/svn/*'`
 }}}

 > So we may be better off advising people to set `core.abbrev` in git
 clone to 8. We could have bootstrap warn if it's in a git clone with the
 default (`git config core.abbrev` will return the empty string). I'm
 unaware of any way of "pushing" configuration on clone.

 I've just written a simple check for the value and then if it's < 8 and
 not set on the repo itself, to set it to 8 on the repo.  But if we already
 have collisions at length 8, that's clearly too short.  I think we should
 go with 12 - that's not so long as to be clumsy, but long enough that we
 are unlikely to see collisions for a significant time.  Using the full
 SHA1 is preferable in places (e.g. commit messages and the backporting git
 notes I've recently started adding).

 > I'm not convinced from the trac ticket that they'll get to it any time
 soon unless someone chips in.

 I'm happy I've at least led that horse to water.
